ALFRED W. REINOEHL, F PHILADELPHIA, PENNSYLVANIA.

A ERQPLANE.

`Application filed January 16,

To all whom 'it may concern:

Be it known .that I, ALFRED iV. REINOEHL, a .citizen of' the UnitedStates, residing at and Stateof Pennsylvania, have invented certain newand useful Improvements inl Ateroplanes, of which the following is aspecification.

My invention relates to improvements in aeroplanes, the object. of theinvention being tov provide a machine of this character, which willembody a maximum of strengths and lifting power, with a ininiinnin'ofparatively inexpensive in construction.

.A further object is to provide an iniproved frame work for holdingtaut, canvas coverings.

A further object is to provide propellers at opposite ends o'tl theaeroplane, driven in opposite directions. V

.A further object. is to provide improved means, whereby air may bc.permitted to passbetween the sections of the aeroplane when desired.

A further object is .to provide improved mounting tor wheeled trucks toguide the A further object is to provide vimproved steering mechanism.which enables the rudder-to be moved in four directions.

A further object. Vis to provide an iin- 'proved canvas covering for theaeroplane desi-red to repair or replace the same.

lith these and other objects in view, the invention consists in certainnovel features of construction, aid combinations,- and ai rangements ofparts as will be more fully hereinafter described and pointed ont in Inthe accompanying drawings, Figure 1, is a top plan View. illustrating myiinprovein ents. Fig. .2. is a view in side elevation. Fig, Ii. is aview in longitudinal section. a view in cross .section on the line 4 4ot Fig. and Fig. 5, is an end view.

for convenience of description, I have givenV the reference letters A, Band C.

The sections A and C are surrounded by canvas sheets 4 and 5respectively, said sheets disposed equally on both sides ot' the upperlongitudinal rod l, thence drawn tightly` around the side rods l, andhaving pei-torated edges to receive lacing cords (3 to tighten thecanvas around the frame, thus holding it perfect-ly` taut without theeniployment ot' any side rods or 'fraine work connecting the rods l. Y

The canvas sheete surrounding section A. is preferably made with anintegral section T to inclose the upper halt` ofthe section B. Thiscanvas sheet or section 7 is attached to'the frame lat the juncture ot'the cross rodY 3 with the rods l atthe' forward end ot' section B, andis of greatest width at its rear end, so that when let't free, the aircan pass upward through the sections l and escape between the rear edgeot the canvas T andthe forwardend of the canvas 5. To'hold this canvastaut during the normal opera tion of the aeroplane, I have provided aneye Sa on the vertical rod 2, and passed a cord 8 through,V said eye.This cord is divided, and its ends are secured to the canvas sections 7at points equi-distant from the center thereof, so that when the cord.is drawn downward through the eye, it will draw this canvas together,causing a central surplus portion to fall over upon the main .portion ofthe canvas, as clearly shown at.

8*? in Fig. 4. This cord will ot' coursebe held in any approved manner,and only released when the aero lane is falling, to check the fall.In-.whici case, the canvas section 7 will be bulged-.out (when permittedby the cord) by the pressure of the -air passing through the sect-ion B,which will cause the aeroplane,- to right itselt' and descend gracefullyto the ground. All ot' these'canvas sections 4, and@ are provided atopposite sides, at points corresponding to the position of the side rodsl, with flanges 10. carrying a series ot' buttons All to which the wingportions D, also of. canvas, are to be.' buttoned, or tirinly secured inany other manner.' These wingsI D are hcld in extended position by meansol upper and lower wire 4stays 1Q and 13 respectively. three up per andthree lower stays provided at both sides being amply sntticient. Theforward the aeroplane.

upper stays extend from a forwardly` projecting end of the upper rod 1,and the canvas section 4 is so shaped as to provide a forwardlyprojecting awning like ortion 4, as clearly'ishown in Figs. 1, 2 an A3.

In the intermediate section B, the operators platform 14 is suspendedfrom hanger rods 15, the latter secured to the cross rods- 3, and arepreferably slightlyuat an incline as shown, to prevent any swmgingmovement of the platform. This platform supports a motor 16, which turnsa gear ,17.

18 and 19 representforwardly and rear# wardly projecting shafts,carrying at their forward and rear ends, propellers 20 and21'respectively. These shafts 18 and 19 are provided with intermeshinggears 22, with one of which the driving gear 17 engages,

so as to transmit motion from the motor to the shafts and drive 'them inopposite d1- rectio'ns. By this means the rear propellerf will `bettertake hold o f the air, than would be the case, if it were driven in thesame direction as to the front propeller, and greater power for flightis thereby attained.

' At the rear of the machine and connected by a universal'joint 23,.ismy improved rudder 24, of the four bladed type, having a weight 25, onits outer vend as shown. Steering cords .26,- 27 and 28 respectivelyconnect the upper portion vand the side portions of 'the ru der with apoint adjacent' to the platform; 14,-.,so as toJ allow the operator onthe platform iso-manipulate these three cords to change the dispositionof the rudderand to ste'erthe machine through the air. The f weight 25serves to draw the propeller downi ward, Whenif permitted by the cords,and

hence a lower cord is not provided, as it would interfere withtheworking portion of,

' On the lowest longitudinal rod 1, near its forward end,"a'n'd atapoint in rear 'of its centen-devises 29 .areadjustably secured,

and are secured. uponexles 30,the latter" mounted in wheels 31, andthese axles are. braced by lrods '32 connecting them' with cross rods 3,so as to prevent pivotal' move-4 ment of the'axles".` -These wheels areto' support the aeroplane on the und in starting, and alighting, andanincihe deflectin lbar 33 is secured at -.one end to the rear ax e 30,and is braced at; itsforward end by a depending rod 34,! at the rearendh of the maj chine. This bar 33 when Athe aeroplane is coming/:t theground with -its front encl elevated, will strike the ound and deflectthe aeroplane do`wn upon its wheels.

A great many slight changes might 'be made in the general fD of partsdescribed, withoutdeparting from,
